摘  要:
研究不同水分处理对春小麦滴灌水分在土壤中的分布状况、水分利用效率(WUE)及产量的影响。结果表明,不同水分处理对滴灌小麦土壤水分的分布有很大影响,同一土层0~20cm土壤含水率在灌溉前后具有明显的变化;0~40cm土层土壤含水率整体趋于平缓,总体表现为W1处理(150mm)

摘  要:
Field experiment was conducted to study the distribution conditions of moisture in soil of spring wheat at experimental station of Shihezi University in 2009,which included 5irrigaiton intensities(W1:150mm,W2:300mm,W3:450mm,W4:600mm(drip irrigation),CK:600mm(furrow irrigation)and 2wheat varieties(Xinchun No.6and Xinchun No.22).Soil moisture at the depth of 0-60cm was detected by using watermark during wheat growing season.Results showed that soil moisture increased with irrigation amount,and there existed obvious variation of soil moisture at the depth of 0-40cm before and after irrigation.The highest and lowest WUE was obtained at W3〔9.42-10.39kg/(mm·hm2)〕and CK〔6.61-6.68kg/(mm·hm2)〕,respectively.Grain yield first increased then decreased with irrigation amount in these two varieties.
